I created a new issue tonight but did NOT send it yet because I was waiting on one more piece of information. All of a sudden about an hour later I started getting email that the newsletter was going out. How do I stop it???

I tried to change the setting in Settings to put it into test mode but received the following error:

I found a fix based on GAB, on line 202 change the =& to just an = sign and that fixes the problem. I don't know WHY it is a problem now when it wasn't before but I was now able to put my site into test mode so hopefully the emails will stop!
